The hard-fought peace Angel and her friends had enjoyed has been shattered by the forces conspiring against them. Now they are up against their greatest challenge yet-preventing the end of the world. As the Daughters race against the doomsday clock, the human world braces itself for unprecedented destruction and strife after Haniel's opening of the Seals. If this wasn't enough, the global Daughters of the Watchers, led by the two-faced London group, have marked the New York group for eradication. Angel and her friends are surrounded by enemies. The Star of Nimrod has found unexpected allies that will bring its quest of eliminating all hybrids ever closer to fruition, and the Sons of the Damned have risen again at Diablos' command. However, the New York team and their Lancaster counterparts have not lost hope. On the contrary, they have become the world's last beacon of light. Can Angel and her friends defeat their adversaries? Or will they succumb to their enemies as the world crumbles around them?
